I was started on Bactrim 7 days ago. The first two days I felt fine, but the 3rd night I got cold...very cold and could not stop shaking for about two hours. My heart was racing and I was nauseated and couldn't focus. This went on for about 8 hours before going to the ER. Upon arrival I had elevated BP and pulse, but after a couple of hours it went down to normal. I saw a new doctor who said it sounded like I had a hypoglycemic attack!! I never had one of those before!! So, I'm figuring I'm getting sicker and maybe it is not from the Bactrim so I take it again and last night was another horrible night!! Racing heart, confusion, and urinating every 30 minutes. Thinking maybe I'm having another attack I get up and eat some applesauce and my husband gives me some sweet tea. I promptly threw up a few times and then we went to the computer to look for ourselves the side effects of this drug. Guess what? It causes hypoglycemia, racing heart, confusion and does something to your kidneys and makes you urinate too much and could be very dangerous!! That was it for me!! I didn't sleep the rest of the night but slept on and off during the day and felt like myself today for the first time since taking the drug. I don't know if it has done any permanent damage, but I will let everyone I know about this awful awful drug!!

Jennj - Yes, this is an strong medication w/ the potential for deadly reactions!! I took this 10 years ago, and it almost killed me! I found out I am very allergic. It had made such a impact on my life I am still googling it on occasion to see other peoples reactions. I was one of the lucky ones, the doctor said. I was a healthy 33 year old with a sinus infection, and the Bactrim given to me by a PA filling in for my Prim. Care DR,could have killed me. After 3-4 days of taking it I was admitted to the hospital for 5 days to receive high doses of steroids to detox my body of the drug. Thanks to the FAST reaction of my dotor and an infectious disease specialist, I was admitted to the hospital immediately and had every test done imaginable. At time of admission my bp was very very low, and my liver was shutting down. Upon arriving I had 3 nurses meet me at the elevator, and they started taking blood out of each arm and hooking me up to iv bags. I was getting the royal treatment from the nurses because ICU was already full, and my mini ICU was in a private room. -My fever was so high I was put on a cooling blanket, and turned every 20 minutes. My body was so sore, I could not move without pain! My skin burned off, peeling everywhere, yuck! All the tests done were negitive, leaving a severe allergic reaction to the Bactrim to blame! --Weeks after recovering, and 8 thousand dollars in hospital bills later, the specialist said "we are lucky we didn't lose you!" If you were an older person, you could have died. YIKES!!! I had 2 toddlers at home, and to think a cheap antibiotic could have left them without a Mommy,make me so angry, still! BEWARE...BEWARE...BEWARE!!! Listen to your body-STOP if you have any funny side effects at all! They could quickly turn much worse NEVER take this dru again if you have had a bad reaction, the next time will be worse.
